BOILER-FEEDER.

SPECIFICATION formingpart of Letters Patent No. 264,209, dated. September 12, 1882.

Application filed May 31, 1832. (No model.)

To all whom it may concern:

Be it known that I, DAVID C. WALTER, a citizen of the United States, residingat Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Im provements in Automatic Boiler-Feeders, of whichv the regulating-valve and chamber, and Fig. 4

is a detail view.

a represents a bed-plate, which is supported on standards a, extended from base a 1) b represent steam-cylinders, which are supported in arms .or brackets extended from bedplate a. These steam-cylinders are properly connected by pistons, piston-rods, and eccentrics and cranks to give motion to the crank b, which is connected by pitman b to piston of pump b by which water is pumpedinto the boiler in the operation of the device, as will be described.

b represents a pipe leading to the watersupply, and b represents the boiler feed-pipe.

1) represents the exhaust-pipes from steamcylinders b.

crepresents the float-cylinder chamber. It is seated on' bed-plate a, alongside the boiler, with its upper end projected above the waterline of the boiler, and it is connected thereto by pipes, as will be described.

e is a pipe connecting the lower part of cylinder c with the lower part of the boiler, which is arranged alongside. p

0 represents a pipe connecting the upper part of float-chamber with the upper portion or steam-chamber of the boiler.

0 represents a water-gage secured to float chamber.

d represents a valve-casing extended from and opening into the upper end of the floatchamber.

at is an exit-port through upper side of the val ve-casin g, to which is seen red the whistle d.

d is an exit-port through lower side of valvecasing, to which is secured the pipe 11*, which conveys steam to chambers b in the operation of the device, as will be described, and in which is provided the throttle-valve (1 The valve-seats in this casing d are inclined from front to rear, as shown in Fig. 3.

6 represents the valve. It is composed of the two wings 0 c which are tapered, as shown, to correspond to the inclinein the valve-seats. This construction is designed to permit the valves to be kept screwed up by screw 0 as they or the valve-seats are worn, thus keeping atight fit.

e is the valve-shaft. It is passed through a metallic stuffing-box in front of the valvecasing, as-shown.

c is a knob secured to outer end of shaft 6*.

f is a balance rod passed through opening in knob 0 and resting at right angles to shaft 0.

f f are weights secured to the ends of rodf.

f is a hand-screw passed through front of knob 6 and arranged to bear against rod f and secure it at any point desired.

g is a graduated are secured to a rod extended out from top of valvecasing.

g is a hand or pointer secured to knob 0 and extended up adjacent to and in front of arc g. By shifting'this rod from one side to another the valves may be regulated without reference to the float hereinafter described.

71. represents the cylindrical float, constructed to move easily up and down in the chamber or cylinder 0, and so that it will float in the water, as shown in Fig. 2.

It represents a rod extended from the shaft of valve 6, at right angles to the said shaft, over the center of cylinder 0.

71. is a connecting-rod swiveled to rod 7t, and extended to and connected by swivel-joint to float It. Thus the float and valve are connected and act together, as shown.

I provide the steam-pipe c and water-pipe c with stop-cocks for cutting ofl' all connection with the boiler in case of repairs.

The pipes c" c and throttle d all being open and the water in the boiler at its proper height, the device is ready to operate. As the water is evaporated and descends in the boiler the water in the chamber will descend also, turn- I and connecting-rod h substantially as and for ing the valve till the wing or cut-off 0 moves past port (1 Steam being received from boiler through pipe 0, now passes through port (1 and pipe d to the engine below, and the pump begins to work, forcing the waterinto the boiler through pipe I). This continues until the wa ter in the boiler and chamber 0 rises, carrying the float up and turning the valve till wing e closes the port at and stops the engine at highwater line. There being a steam-port, e, at upper side of chamber (1, in casethe water rises too high the wing or cut-offd would pass the port 6 and admit the steam to the whistle d causing an alarm for high water; and, on the other hand, as the water descends, should it not stop at its proper point the cut-off 61 would pass the port 0 and give alarm for low water. I use the two cylinders b in order to overcome the dead-center and give a positive motion to the pump.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with the float-cylinder c and the float h, of the valve-box d, placed near the upper end of and opening into the float-cylinder, and having the exit-ports d (P, arranged opposite to each other, the valve 0, having the opposite Wings, 0' 6 opening or closing the ports d 61 the valve-arm 7L, extended from the valve into the float-chamber,

the purposes set forth.

2. The combination, substantially as hereinbefore set forth, of the float-cylinder, the valvecasing placed near and laterally to the upper end of and opening into the float-cylinder, and having port (1 opening upward and the port 01 opening downward, whistle 01 valve 6, having wings 0 e placed in the casingd and opening or closing the ports (1 d the valve-arm h, extended into the float-cylinder, float h, coupling 7L pipe (1 and steam-cylinders b b, substantially as set forth.

3. The combination, with the float-cylinder a, lateral valve-case d, float h, valve 6, and suitable rods and arms connecting the valve with thefloat, of the steam-pipe (1*, cylinders b b, the piston-rods operating the pistons in cylinders b b, crank b, and the pump mechanism, substantially as set forth.

4c. The combination, substantially as described, of the casing d, the valve 0, placed within and havingits shaft 6 extended through the end of said casing, knob 6 and rod f, having weights on its opposite ends, and clamping-screwsf as described.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID C. WALTER.
